PTC Motor Protector TMP6500-A1

The TMP6500 is a thermistor motor protection tripping unit, which protects a motor or a transformer against thermal overload. It is designed to monitor the temperature of electric drives, transformer windings, bearings etc. in conjunction with PTC Thermistors that follow the DIN 44081-44082 standards (single or triple sensors).

TMP6500 is connected with the motor-embedded PTC thermistors and uses their abrupt resistance increase as a control signal for the tripping unit. When the nominal response temperature (TC) is exceeded, the sensor acts as a thermal switch and activates a relay output for any use (disengagement of the load's power supply, alarm activation etc). When an acceptable temperature level is restored, the sensor resistance decreases to the reset level and the module permits either automatic or manual reset.
